The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. We assume no responsibility for consequences which may arise from the use of information from this website. Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure.
